SULKY.

SEEOIFIGATION forming part of Letters Patent N0- 545,4'76, datedSeptember 3, 1895.

Application filed May 25,1893. Renewed May 25, 1895. Serial No. 550,718.(No model.)

To all whom it may concern:

Be it known that I, EDWARD S. FRAZIER, a citizen of the United States,residing at Aurora, in the county of Kane and State of Illinois, haveinvented certain new and useful Improvements in Sulkies, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which Figure 1 is a rear View, Fig. 2 is a side elevation,Fig. 3 is a plan view, and Fig. 4 is a rear view, of a modified form ofthe axle.

My invention relates to sulkies, and particularly to that class commonlyknown as bicycle-sulkies, in which the sulky is provided With'smallwheels provided with pneumatic tires.

The principal object of my present invention is to provide a sulky ofthe class described which will be provided with an axle which will belight, strong, and durable. Heretofore sulkies have been provided withaxles commonly known as trussed axles, or with axles formed of twocurved members, one placed within the other, their ends extendingdownward on opposite sides of the wheels and carrying wheel-spindles,the two members of the axle being braced by short braces placed atsuitable intervals apart. This lat ter construction has been found to belacking in durability and strength, and my present invention is designedto provide an axle which will be superior to those above referred to.

Another object of my invention is to provide a new and improvedsingletree.

I accomplish these objects as hereinafter specified and as illustratedin the drawings.

That which I regard as new will be set forth in the claims.

In the drawings, 5 indicates a sulky, of which 6 indicates the seat, 7the shafts, and 8 the wheels.

9indicates the axle, which is composed of two curved members 10 11, ofdifierent degrees of curvature. The curved members 10 11 are placed atan angle to each other, as shown in Fig. 2, and carry the seat 6, asshown, the member 10 supporting the front portion of the seat and themember 11 the rear portion thereof. The lower ends of the members 1O 11lie in the same line and carry the wheel-spindles 12, as shown inFig. 1. The

wheels 8 are adapted to be mounted upon the wheel-spindles and to turnbetween the lower ends of the members 10 11, as shown in Figs. 1 and 3,the ends of the member 10 being on the outside and the ends of themember 11 on the inside of the wheels, or vice versa. The rear portionof the shafts 7 passes between the members 10 11, and is securedthereto, as shown in Fig. 2.

13 indicates external braces, which extend from the wheel-spindles 12 tothe shafts 7, as shown'in Figs. 2 and 3.

14. indicates internal braces, which are socured to the inner ends ofthe wheel-spindles and to the shafts 7, as shown in Fig. 3.

By the above construction an axle is produced which is very light andwhich is also very strong.

15 16 indicate a pair of bell-crank levers, which are secured atopposite sides of the sulky directly to the shafts or upon suitablesupports. The rear arms of the levers 15 16 are connected by a wire 17or other suitable connecting device, as shown in Fig. 3. The traces areadapted. to be secured to the free ends of the levers 15 16. By thisconstruction the force of the draft will be exerted upon the wire 17,and,owing to the elasticity of the wire, the singletree will yieldslightly when the draft is first applied. This construction tends toprevent jerking or straining of the sulky from starting suddenly. It isalso very light, which is an important advantage.

In Fig. 4 I have shown one of the members, as 11, provided with a truss18 and braces 19. This construction may be used for one or both membersif extraordinary strength is desired.

That whichI claim as my invention, and desire to secure by LettersPatent, is-- '1. A sulky axle consisting of two curved members arrangedat an angle to each other, and wheel spindles supported between thelower ends of said members, substantially as described.

2. In a sulky, the combination with an axle composed of two curvedmembers 1011 arranged at an angle to each other, of wheelsjournaledbetween the lower ends of said members, a seat mounted upon theupper por- IOO tions of said members, and shafts, substanshafts, andexternal and internal braces for tially as described. the ends of saidmembers, substantially as 3.
